Port Powered BB-485SD9RJ RS-232/RS-485 Converter Features Extend RS-232 data signals up to 1.2 km (4000 ft) Convert RS-232 TD and RD to RS-485 signals Automatic Send Data Control - no software drivers necessary Baud rates up to 115.2 kbps Powered from RS-232 handshake lines - no power supply required Introduction Ordering Information This port-powered, two channel converter allows your computer to communicate longer Model No. RS-232 Connector RS-485 Connector Output distances by converting TD and RD RS-232 lines to RS-485 signals. RS-485 also provides multi-drop capability. BB-485SD9RJ DB9 Female RJ11 RS-485 2-wire Model BB-485SD9RJ features Automatic Send Data Control which enables the driver when data is present on the RS-232 side. Control of the driver is automatic at speeds up to 115.2 kbps. Accessories Sold Separately BB-9PAMF6 - DB9 Male to DB9 Female Adapter Cable, 1.8 m (6 ft) The unit is powered from the RS-232 data and handshake lines whether the lines are high or low. No handshake line change is necessary to control the data lines. The RS- 485 driver is enabled with each bit of data. The RS-485 receiver is disabled when the driver is enabled and is enabled when the driver is disabled. Model BB-485SD9RJ is suitable for field service, where a power supply would add clutter, or anywhere you need compact, easy-to-use, economically priced serial conversion. Automatic Send Data Control Explained As operating systems become more complex, it is increasingly difficult to control an RS- 485 driver with standard software and the RTS line. This is especially true in Windows and multi-tasking operating systems. With Advantechs Automatic Send Data Control circuit, driver control is in the converter hardware, so you do not have to work with software at all. The circuit monitors data flow and enables the driver during transmission and automatically disables it when no data is being sent. There is no need to rework software or install new drivers. Most Advantech RS-232 to RS-485 converters and RS-485 serial cards include Automatic Send Data Control.
